s .Clairns. (01.1 491 -52 The object of this invention is to provide a glass cutter of noveL- simple and. efiicient construction having a unit consisting of a cutting disc and a carrier therefor which may be readily applied to and removed from the body of the cutter; having means which is operable to facilitate the removal of the unit from the body of the cutter; and having means for enhancing the wearresisting qualities of the entire device.

With the foregoing and related objects in view, the invention consists of the elements and the I combinations of them hereinafter described and claimed.

In the accompanying drawing, illustrating the invention,

Figure 1 is a side View of a glass cutter constructed in accordance with my invention.

Figure 2 is a top view thereof.

Figure 3 is a top view of the cutting end por-- tion of the device, enlarged.

Figure 41s alongitudinal section through the device, on lined-4 of Fig. 2, enlarged.

Figure 5 is a transverse section through the device, on line 5-5 of Fig. 1, enlarged.

Figure 6 is a detail, showing the unit removed from the body of the device and enlarged.

Referring to, the drawing,'the body of the device comprises a cutting head 2 and a handle 3 extending from one end thereof, shaped as illustrated in the drawing andpreferably formed of cast iron. 1

The head 2 is provided with an embracing sheath 6 which extends over and down the re-v spective sides of the same and which is preferably secured thereto by electric welding or other suitable means. The sheath 6 is formed of sheet steel or other suitable wear resisting metal which is harder than the metalforming the head 2.

The free end of the head 2 is provided with a kerf 7 for the reception of the cutting disc 8 which is of usual construction. The top part of the sheath 6 is also provided with a kerf 9 in registry with the kerf '7 in the head for receiving the cutting disc 8 which extends into the two kerfs.

A longitudinally extending slot 10 is formedby and between the bottom surfaceof the upper portion of the sheath 6 and the top of theforward end portion of the head 2. The forward end of the slot 10 in the region of the cutting disc 8 is open and the rearward end thereof is closed by a shoulder 11 formed by the head 2. The sides of the slot 10 are closed by the downwardly extending sides of the sheath 6 which form opposed side walls for the slot.

I The slotlOis wider than the kerfs '7 and 9 and it extends. laterallyfrom me. respective sides thereof and it opens into the same. I

The cutting disc 8 is carried by a carrier 12 which is seated in the slot 10 and which with the disc 8 constitutes a unit, as shown separately in Fig. 6, which may be easily and quickly applied to or removed from the cutter head 2.

The carrier .12 is formed of a single piece of resilient wire and it comprises a shaft portion 13 on which the cutting disc 8 is rotatablymounted, and a- V-shaped arm 14 having one of its side members 15 extending fixedly from one end of the shaft portion 13 and having the other of its side members 16 extending back toward and terminat- Z0 ing in advance of and in close proximity to the nearest side of the shaft portion 13, as clearly shown in Fig. 6.

The cutting disc 8 is rotatablymounted on the shaft-portion 13 and it extends between the side members 15 and 16 of the carrier and is thereby retained in place upon the shaft portion. The disc 8 may be readily placed upon or removed from the shaft portion 13 after the free end of the side member 16 has been sprung outwardly from the free end of the shaft portion 13 sufficiently to permit the disc to be passed between them. 1

The side members 15 and-'16 of the arm li'diverge from their connected ends to the ends 3 thereof adjacent to the disc 8 and the distance between the outer sides of the members 15 and 16 for some distance from the shaft portion 13' is greater thanthe space between the opposed side walls of the slot 10, so thatwhen the unit is in- 590 serted into the slot, as shown in Figs. 3 and 4, the side members 15 and 16 will be sprung toward each other and thereafter hold the unit in place within the slot 10 by the pressure of the members 15 and 16 against the side walls of the slot, as the members tend to resume the more widely spaced relationship from which they were sprung.

When the unit is inserted into the slot 10, the cutting disc 8 is entered into the, kerfs 7 and 9, the width of which is substantially equal to or slightly in excess of the thickness of the disc 80 that the side walls of the kerfs maintain the disc at right angles to the shaft portion 13.

Slidable longitudinally in the slot 10 to and from the shoulder 11 at oneend thereof is a T-shaped thumb piece or part 17 which extends through and above a'slot 18 formed in the top of the sheath 6, and when the carrier 12 of the unit is inserted into the slot 10 the carrier moves forms a stop, limiting the inward movement of the carrier when it is seated within the slot 10.

When it is desired to remove the disc 8 and carrier 12 from the slot 10, the part 17 is moved by hand toward the free end of the head 2, thereby moving the disc 8 and carrier 12 outwardly from the free end of the head 2, from which the unit may then be easily and quickly withdrawn by hand. V

The use of the sheath 6 enables me to provide substantial wear resisting supporting walls for the sides of the cutting disc 8.

I claim as my invention:

1. In a glass cutter, a body having a kerf and a slot therein, a carrier seated in and removable from the slot, a cutting disc rotatably carried by the carrier and extending into the kerf and a part movably connected to the body and operable to move the carrier from its operative position within the slot, said part being provided with means to prevent its removal from the body.

2. A unit for a glass cutter, consisting of a carrier formed of a single piece of wire comprising a shaft portion and a U-shaped arm having one of its side members extending fixedly from one end of the shaft portion andhaving the other of its side members extending back toward and terminating in advance of the nearest side of the shaft portion and a cutting disc rotatably carried by the shaft portion and having a part thereof extending between the side members of said arm, said side members preventing accidental displacement of the disc from the shaft portion.

3. A unit for a glass cutter, consisting of a carrier formed of a single piece of wire comprising a shaft portion and a U-shaped arm extending from one end thereof and a cutting disc rotatably carried by the shaft portion and having a part thereof extending between the side members of said arm, said side members preventing accidental displacement of the disc from the shaft portion.
